Impact includes members in approximately grades 9 through 12 and is an intermediate performance ensemble. Impact members audition for instrument placement. They rehearse advanced cadences and percussion pieces, learn marching techniques and will perform at events in the Sioux Falls area.

Starting in November and running through April, rehearsal for Impact will be held on Thursdays from 6:00 pm to 9:00 pm at the Sioux Empire Fairgrounds Armory Building (directly north of the Grandstands). All rehearsals will be held at this location unless there is a scheduling conflict. Notice of any changes will be placed on the website and sent out via email as soon as that information is made available. Check the Events Calendar regularly for location updates.

The Impact uniform will be based on the show theme and included in the dues payment. All dues/uniform costs must be paid timely.
